Delete files containing jdbgmgr.exe that were sent to her through email?

A friend received a notice to delete files containing jdbgmgr.exe that were sent to her through email. I search my files and found two files containing jdbg items. I have moved these to the trash and am now wanting to know if the trash should be deleted. Many times you get these type of notices and then find out they are a hoax. Just wanted to check before I created a problem for myself. Thank you.
